Jump to: navigation, search

The grubby chest can be found on the south-west corner of the Forthos Dungeon, behind a locked gate that requires level 57 Thieving to open. The chest is locked and can only be opened by using a grubby key, which is obtained from killing monsters in the Forthos Dungeon. There is a warning message when attempting to open the chest with less than 11 free inventory spaces, which can be disabled.
